Abstract

In this study, we sequenced and analyzed the complete mitogenome of Marumba saishiuana Okamoto, 1924. The complete mitogenome sequence of M. saishiuana is circular, 15,662 bp in size and encodes 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNAs), 22 transfer RNA genes (tRNAs), and a control region (CR). Nucleotide composition is highly biased toward A + T nucleotides (81.2%). Most of 13 PCGs initiate with the standard start codon of ATN, except cox1, which starts with CGA. Phylogenetic analyses were performed using nucleotide sequences. A total of 32 Smerinthinae species were selected. The topology based on mitogenome showed that M. saishiuana, M. gaschkewitschii, and M. sperchius formed a clade, and this indicated that M. saishiuana was a member of genus Marumba. Polyptychus trilineatus was the most closely related to genus Marumba on the phylogenetic tree reconstructed by mitogenomes.
